Giardia lamblia (synonymous with Giardia intestinalis, Lamblia intestinalis and Giardia duodenalis) is a flagellated protozoan parasite that colonises and reproduces in the small intestine, causing giardiasis. The giardia parasite attaches to the epithelium by a ventral adhesive disc, and reproduces via binary fission. Giardiasis does not spread via the bloodstream, nor does it spread to other parts of the gastro-intestinal tract, but remains confined to the lumen of the small intestine.

Back in In the issue of 23 October 2009, Science published a study by Lombardi et al. purporting to show that a retrovirus called XMRV (xenotropic murine leukemia virus-related virus) was present in the blood of 67% of patients with chronic fatigue syndrome (CFS) compared with 3.7% of healthy controls.[1]

This as everyone will recall, attracted a great deal of scientific and patient derived interest, but there has been considerable lack of success in the replication of these findings by other investigative groups.

Abstract

The NO/ONOO− cycle is a biochemical vicious cycle that is thought to cause such diseases as chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), multiple chemical sensitivity (MCS), fibromyalgia (FM), and possibly a large number of other chronic inflammatory diseases. The chemistry/biochemistry of the cycle predicts that the primary mechanism is local such the depending on where it is localized in the body, it may cause a variety of different diseases. Previous studies have shown that agents that lower such cycle elements as oxidative stress, nitric oxide, inflammatory responses, mitochondrial dysfunction, tetrahydrobiopterin (BH4) depletion and NMDA activity produce clinical improvements in CFS/ME and FM patients, consistent with the predictions of the cycle mechanism. Multiagent protocols lowering several aspects of the cycle appear to be the most promising approaches to therapy. These include an entirely over-the-counter nutritional support protocol developed by the author in conjunction with the Allergy Research Group. However, such

BACKGROUND: Human herpesvirus-6 (HHV-6), Epstein-Barr virus and parvovirus B19 have been suggested as aetiological agents of chronic fatigue syndrome but none of these viruses is consistently detected in all patients. However, active viral infections may be localised in specific tissues, and, therefore, are not easily detectable. The aim of this study was to investigate the presence of HHV-6, HHV-7, EBV and parvovirus B19 in the gastro-intestinal tract of CFS patients.
